The “Cutie Map” is introduced in My Little Pony: Friendship is Magic, Season 5 Episodes 1 & 2, in the eponymously titled 2-parter, “The Cutie Map, Pt. 1” and “The Cutie Map, Pt. 2.”
The Cutie Map is introduced as a new magic power, available to the Mane 6 characters — Princess Twilight, Rainbow Dash, Pinkie Pie, Rarity, Apple Jack, and Fluttershy — which shows where their powers are most needed, as reflected by their Cutie Marks. It is essentially a magical holographic map of Equestria which shows places in need of help.
In this case, it was long established that each of the Mane 6 are the bearers of the Elements of Harmony:
Princess Twilight: Element of Magic
Rainbow Dash: Element of Loyalty
Pinkie Pie: Element of Laughter
Rarity: Element of Generosity
Apple Jack: Element of Honesty
Fluttershy: Element of Kindness
The Cutie Map shows a location where all six Cutie Marks are congregated, reflecting at least a location which is bereft of magic, loyalty, laughter, generosity, honesty, and kindness — all at the same time and place.
The location is a Pony town led by Starlight Glimmer, who has convinced the entirety of the towns’ residents to give up their own Cutie Marks, thereby having them replaced by “=“ representing that all of the ponies are equal, none have any individual trait the others don’t have.
Is the in-universe supernatural and magical recognition through the Cutie Map of the concept of equality as exercised by Starlight Glimmer in the form of voluntarily foregoing one’s own individual traits separating oneself from others, objectively mean that such form of equality is an all-hands-on-deck problem which needs the immediate application of magic, loyalty, laughter, generosity, honesty and kindness? In Ponyverse is such equality an unkind, disloyal, or fraudulent concept?
